COLLAPSIBLE OR KNOCKDOWN BOX.

Application filed May 31, 1913.

To all whom it may concern.

Be it known that I, Josnrn IV. Weiss, a citizen of the United States,and a resident of Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Collapsible or Knockdown Boxes,of which the following is a specification.

This invention relates to collapsible boxes or cartons, moreparticularly to the type known as the slotted carton. A collapsiblecarton of this character is usually formed of an integral sheet offibrous material having quadrilateral sides and end flaps which formclosures for the ends of the box. The material of which the box is madeis necessarily light in weight, and, therefore, is not suflicientlystrong to resist shocks and wear incidental to its transportation fromplace to place while containing goods packed therein having anyconsiderable weight. To overcome this difficulty due to the inherentflimsiness of construction of the collapsible slotted carton, I attach acushioning rib, formed preferably of resilient material, to the sidesadjacent to the junction of the sides and end flaps. This rib bears thebrunt of the knocks, and owing to its resiliency, cushions the blowtransmitted to the body of the box and thus prevents injury to thelatter due to the sudden shock or blow. The rib may be formed of anysuitable material calculated to produce the cushioning effect. I prefer,however, to form the same of fibrous material having the variousportions thereof so disposed as to produce the necessary resiliency.

Referring to the drawing illustrating the preferred embodiments of thisinvention, Figure 1 is a perspective view of a slotted carton with myimproved cushioning ribs applied thereto. Figs. 2, 3 and 1 are detailviews of sections of various forms of ribs which may be used. Figs. 5, 6and 7 illustrate in perspective fragments of other forms of ribs whichmay be used. Fig. 8 is a section showing a modified form of carton inwhich the end flaps may form continuations of said cushioning ribs. Fig.9 is a fragmental perspective view of a modification in which cushioningribs are also attached adjacent to the longitudinal edges as well asadjacent to the end edges of the box.

Referring particularly to Fig. 1, the carton or box may be formed of asingle integral sheet of material having sides 10 and Specification ofLetters Patent.

end flaps 11 forming closures for the ends of the box. -Adjacent to thejunction of the sides and end flaps may be attached in any suitablemanner as by staplin sewing or pasting, a resilient rib 12 preferablymade of fibrous material so disposed as to obtain such resiliency orcushioning effect.

In Fig. 2,'I have illustrated a section of rib consisting of two walls13 and 1 1 between which is disposed a sinuous or corrugated spacingmember 15, the corrugations running lengthwise of the rib. To protectthe raw edges, I have preferably pasted or otherwise attached, suitablefinishing strips 16 'over the edges. These strips are preferably formedof tape, canvas or some other suitable strong, flexible material.

In the form of rib which is illustrated in cross section in Fig. 3, thesame type of corrugated cushion is used as illustrated in Fig. 2.However, in this construction, the cushioning effect is increased bydoubling the corrugated strip lengthwise upon itself,

thus the walls 17 and 18 corresponding to the walls 13 and 14 of Fig. 2are made of greater width and together with the corrugated spacingmember 19, are folded over at substantially their mid width as at point20.

In the form illustrated in Fig. 4, the

outer walls 21 and 22- together with the corrugated spacing strip 23 arefolded over at two points 23 and 24, thus bringing the edges 25closelytoward each other. hen the rib is attached to the sides of the box,these edges 25 are entirely concealed.

In the modified construction illustrated in Fig. 5, the rib may beformed of a strip of material 26, having a sinuous section and attachedto the sides of the box preferably at mid Width of the strip as bystaples 27. By reason of a certain amount of resiliency in the material,resilient loops 28 and 29 are formed at the opposite edges which producethe cushioning effect.

In the form illustrated in Fig. 6, the re- I be composed of two wallsand an intermediate corrugated spacing member as in the form illustratedin Fig. 2, may be suitably attached adjacent to the end edges of thesides of the box and have the flaps 36 formed therewith and extendingtherefrom. In this way, the end walls of the box forming the closuretherefor are also resilient and further add to the strength of the box.

In the further modified form illustrated in Fig. 9, an added resilientrib 87 may be attached to the sides 10 adjacent to their meeting edges.This may be used as an added precaution in connection with boxes inwhich a large weight is to be carried located close to the mid-length ofthe box, in which case, when the box is thrown on its sides, the ribs 87will support and cushion the intermediate portion of the box bearing themost weight.

It will be seen from the various forms of my invention above described,that I have provided a collapsible box which can receive considerablerough handling and jar without injuring the box itself and withoutdisturbing the contents. Thus comparatively fragile matter may be sentin these boxes without breakage. Also, a heavy load can be carried bythe boxes without danger of bursting the same as the edges are cushionedand when any blow or jar is sustained by the box, it will be taken up bythe cushioning ribs without imparting the whole force to the body of thebox. It will be noted also that these cushioning ribs have the addedfunction of actually strengthening and bracing the box itself.

Having thus described my invention, I claim 1. A collapsible box formedof fibrous material having sides and end flaps extending therefromforming closures for the ends of the box and a. flexible resilientcushioning rib formed entirely of fibrous material separate from thesides and disposed adjacent tothe unction of the sides and flaps, andmeans for attaching the cushioning ribs to the sides, all the members ofthe box continuing in attached relation to each other both when the boxis set up or collapsed.

2. A collapsible box of fibrous material having sides and end flaps anda wave formed flexible resilient cushioning rib located adjacent thejunction of the sides and flaps, said rib being separate from the sidesand having a substantially fiat outer protecting surface, and means forattaching said cushioning rib to the sides, all the members of the boxcontinuing in attached relation to each other both when the box is setup or collapsed.

3. A collapsible box of fibrous material comprising sides and end flaps,a resilient cushioning rib comprising a Wave formed member located atthe exterior surface of the box adjacent to the junction of the sidesand flaps, said rib being separate from the sides and having asubstantially flat outer protecting surface, and means for attachingsaid cushioning rib to the sides, all the members of the box continuingin attached relation to each other when the box is set up or collapsed.

at. A collapsible box formed of fibrous material having side and endflaps extending therefrom forming closures for the ends of the box, anda wave formed flexible resilient cushioning rib located adjacent theedge of the box forming the junction of the sides and flaps, the wavesof said rib extending lengthwise in the direction of said edge, andmeans for attaching said cushioning rib to the sides, all the members ofthe box continuing in attached relation to each other both when the boxis set up or collapsed.

5. A collapsible box formed of fibrous material having side and endflaps extending therefrom forming closures for the ends of tie box, awave formed flexible resilient cushioning rib located adjacent the edgeof the box forming the junction of the sides and flaps and formedcontinuous thereabout, the waves of said rib extending in the dircctionof said edge, and means for attaching said cushioning rib to the sides,all the members of the box continuing in attached relation to each otherboth when the box is set up or collapsed.
